WDM allows transmission systems to:

• A.Transport multiple signals transparently, onto several wavelengths, all together over one single fiber
• B.Increase the bit rate of each client signal by spreading it over multiple wavelengths
• C.Share a single signal among multiple fibers doing load balancing, and thus increasing the reliability of the optical transmission
• D.Allocate different signals to different time slots
